Let's divide 939457 by 78
Let's see how many times 78 fits into 939457.

Let's proceed to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 78

On to step 2:
If we divide 93 by 78, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 93 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 78

Going ahead to step 3:
159 divided by 78 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 156 from 159 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 78

Step 4:
78 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
The remainder is 34 after subtracting 0 from 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 78

Step 5:
78 goes into 345 4 times with a remainder of 33.
The next digit of our result is 4. 
Result so far: 1204.0
The remainder is 33 after subtracting 312 from 345.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 78

Let's proceed to step 6:
If we divide 337 by 78, we get 4 and a remainder of 25.
The next digit of our result is 4. 
Result so far: 12044.0
If we subtract 312 from 337, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
78 can be fit into 250 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 12044.3
Deduct 234 from 250 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 78, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 12044.32
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 78, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 12044.32
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
When dividing 400 by 78, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12044.3205
If we subtract 390 from 400, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
78 goes into 100 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 12044.32051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
When dividing 220 by 78, we get 2 with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 12044.320512
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
78 goes into 640 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12044.3205128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 78, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 12044.32051282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 12044.32051282 with a remaining 4e-09.
